SYSTEM OF SEWAGE DISPOSAL.

To all whom it may concern:

:Beit known that I, FRED P. SMITH, a citizen of the United States,residing at Kansas City, in the county of Wyandotte and State'of Kansas,have invented certain l new and useful Improvements in Systems of SewageDisposal, of which the following, is a specification. v

Iy present invention pertains to improve- -rm, its n sewage disposal,the construction j .wall of the basin at a and advantages of which willbe hereinafter set forth, reference being had to the annexed drawings,wherein:

Figure 1 is a plan of the system employed in carrying out my invention;Fig. 2 a vertical sectional View, on the line 2-2 of Fig. 1; Fig. 3 asimilar view, on the line 33 of Fig. 1; and Fig. 4 a vertical sectionalview on the line 4-4 of ig. 1.

The main object of my invention is to provide a sewage'system in which,under normal conditions, the sewage may be passed through septic tanks,the solids removed and the clarified water free from matter in susjpension subjected to a suitable chemical before being finallydischarged.

A further object is to so construct the apparatus that the clarifiedwater will be periodically discharged and at the same time subjected tochemical treatment.

A still further object is to so construct the apparatus that any excessor surplus of I water, due to rain, may pass out oi the apparatusthrough a suitable by-pass' or overllow, without passing through theseptic tanks and flush tank.

Referring to the drawings, A denotes the sewage inlet, whichcommunicates with a catch-l.)asin B, which in turn communicates with. asediment vat C, through an opening 1), Figs. 1 and 4, located at asuilicient height toinsure the retention of the greater portion of thesolid matter carried by the sewage. An adjustable valve D is providedfor the opening I), in order that the flow of sewage from thecatch-basin to the sediment vat may be regulated as desired.

Specification of Letters Patent.

and- K, to the tanks A screen E extends lengthwise of the catch basin toone side of the inlet and opening l),- and a second outlet F is formedin the point somewhat higher than the outlet 1). As Willi-be seen uponreference to Fig. 1, screen Estands between Patented June 23, 1908.

the inlet and the secondary or overflow outlet Ordinarily the sewagepasses through opening D, but in case of an excessive fall of rain, or asudden frshet, the water will rise in the catch-basin and pass throughopening F into a pipe or conduit G which connects with a main sewer orculvert TI.

Sediment vat C connects through open ings I, I with tanks J, K, whichmay be termed the crude septic tanks. Said tanks in turn are incommunication, respectively, through openings L, L, with tanks M and N,which may be called the clarified septic tanks. Each of the tanks M andN is provided with a retarding wall or bridge 0, located adjacent to theoverflow wall of the tank. Tank N is in direct communication M is incommunication with said flush tank through pipe R. Thus it will be seenthat the sewage passes first into catch-basin B, thence into thesediment vat or chamber 0, to the crude septic tanks J M and N, andlinally into the flush tank P. i The solid matters will thus have achance to separate, and all decomposible substances will be broken upand decomposed in the septic-tanks, so that the water which passes tothe [lush tank will carry all soluble matters but be free from matter insuspension. Each tank, basin or vat will be provided with a suitablemanhole, in order that accumulated matter may be removed.

Flush tank P has a siphon S, ol" any approved type, said siphoncontrolling the passage of liquid from the tank through a pipe T, whichleads to any desired point. The siphon comes into action when theliquiddn the tank reaches a predetermined level, as will be readilyunderstood.

In order to properly treat the clarilied liquid as it passes from theseptic tanks M and N into the flush tank P, an autolnaticchemical-applying device is used. in the upper portion of the flush-tankis located a cylinder or reservoir U, best shown in Fig. 4, saidreservoir being designed to hold crystallized sulfate of copper or thelike. end of said reservoir is comiectedto a service water pipe V, andfrom the upper end of the reservoir projects a perforated pipe W, saidpipe extending across the reservo1r,so as to chamber Q. of tank Thelower .70 with the flush tank P, while the dischargevoir U and containedchemical and force a solution out through the pipe W, thereby sprayingthe surface of the water in the flush tank, which action will continueuntil the water in the tank falls below that level which will cause thefloatto again fall and close the valve. of water which is siphoned offfrom the flush tank is chemically treated, so that all germ life andnoxiousjvapors which might arise therefrom will be destroyed, and thewater which passes from the system into the main sewer or culvert H willbe entirely innocuous and free from solid matters.

Under normal conditions, all the sewage will "psas through the septictanks and the flush tank and be treated in the manner hereinbefore setforth. When, however, al'reshet occurs, the excess water will pass outthrough the opening F and pipe G, so as notto destroy the action of thetanks, which will con-- tinue to operate in the manner above set forth.The screen E prevents any solid matters from passingout through theopening F.

N o -clai in is herein made to thc'particular form of septic tank shown,as this "subjectmatter is reserved for a future application.

While sulfate of copper has been specifieallyinentioned as thcchemicalagent to be used for the treatment of the water resulting from theseptic system, any other germicide and deodorant may be employed.

Having thus described my invention, what I claim is': A o combinationwith a catch-basin It will thus be seen that each charge adapted anddesigned to receive sewage; a septic tank system connected therewith andreceiving the sewage under normal conditions; and a lay-pass or overflowextending from the catch-basin, said by-passor overflow coming intooperation to re ieve the tank system from flooding under abnormal inflowof sewage or rain-water.

2. In combination with a catch-basin adapted and designed to receivesewage; a septic system connected with said catchbasin; an overflowextending from the upper portion of said-catch-basin at a point abovethe outflow for the sewage to the septic system; and a screen for saidoverflow.

3.In combination with a catch-basin adapted and designed to receivesewage; a

septic tank systemconnected therewith; ailush tank connected with theopposite end of the septic tank system; a siphon for periodicallydischarging theilush tank; a reservoir mounted within the fiush tank,said reservoir being adapted to contain a chemical or the like; a waterpipe leading to said. tank; an automatic valve located within said pipe;and a spraying device connected to the opposite end of the reservoir,substantially as and for the purpose described.

In testimonywhereof l have signed my name to this specification in thepresence. of two subscribing witnesses.
